The brushless dc motor (BLDCM) suffers the prominent draw- back of torque ripple, a novel hybrid control strategy based on dc link voltage control and fuzzy PID controller is proposed to suppress torque ripple of BLDCM. The circuit topology contains a power factor correction (PFC) buck converter and a inverter. The PFC buck converter reduces the commutation torque ripple by controlling dc link voltage, the inverter using fuzzy PID controller and pulse width modulation (PWM) technique supplies the appropriate current in the conduction region. The experimental results show the proposed strategy suppresses torque ripple efficiently with the function of power factor correction.
